Abstract: A method for forming an embodiment of a fluid nozzle assembly includes removing two cores in opposed directions from a die set having a mold cavity configured to be a negative replica of the fluid nozzle assembly. The cavity includes the two cores, with one core configured to be a negative replica of: a fluid connector receiving bore; an inlet region of a nozzle; and a pass-through conduit, each in fluid communication with the fluid connector receiving bore. The other core is configured to be a negative replica of an outlet region of a nozzle in fluid communication with the inlet region. Removing the cores forms the nozzle assembly after molten polymeric material injected into the mold cavity has solidified. Removing leaves substantially no flash: at an area where the inlet region and the outlet region meet; and at an end region of the pass-through conduit distal to the receiving bore.

Abstract: This invention relates to windshield wiper system and method which utilizes a flexible member to account for compression loads in excess of a predetermined load, such as 30 percent greater than a maximum load for the flexible member. The system utilizes a flexible pultruded composite material having a relatively low modulus of elasticity, yet relatively high elongation characteristics. The flexible arm bends to facilitate preventing damage to components in the wiper system when a compressive load applied to the flexible member reaches a predetermined load as a result of a fatigue condition, such as snow or ice build up on the windshield. In one embodiment, the predetermined load is defined as: PCR=KE=1.

Abstract: A ball nut has at least one internal bearing race with a first end and second end, and at least one recirculating crossover passage for connecting the first end with the second end of the bearing race to form a continuous recirculating path for a plurality of ball bearings. A method for producing a ball nut includes the steps of forming at least a portion of the ball nut body with a helix passage for receiving a plurality of ball bearings, forming a crossover passage in communication with the helix passage for returning the plurality of ball bearings to an opposite end of the helix passage, and assembling the ball nut body portions to position the helix passage and operable orientation with respect to the crossover passage to define at least one raceway having a single recirculating rotational path for receiving the plurality of ball bearings. The ball nut body can be formed by being drawn, coined, metal injection molded, roll formed, through rolled, stamped and/or overmolded.

Abstract: A gothic-style bearing defines a single circular continuous recirculating path raceway for a plurality of ball bearings to be positioned therein and to be in operable engagement with a shaft having an annular groove formed therein. The bearing includes an eyelet having a cylindrical portion, a flange portion connected to one end of the cylindrical portion, and an annular groove with a ball-engaging surface formed in a transition between the cylindrical and flange portions. Two eyelets are assembled in flange-to-flange, face-to-face relationship with respect to one another and aligned with an annular groove formed in a shaft to be supported to receive a plurality of ball bearings to be positioned therebetween.
